I think Lincoln Loud would be really interesting. He's used to dealing with a large family and all kinds of chaos at home. In the Tokyo Ghoul world, he would have to use those skills to survive among the ghouls. His sense of curiosity and determination could lead him to try and understand the ghouls better, and he might even try to find a way to bridge the gap between humans and ghouls, which is a major theme in Tokyo Ghoul.
Lori Loud could be an interesting crossover character. She's used to being in charge and making decisions. In the Tokyo Ghoul world, she might take on a leadership role among the humans who are trying to survive. She could use her bossy nature to organize the resistance against the more dangerous ghouls, but also learn to be more empathetic as she gets to know some of the ghouls who are not as violent and are just trying to live their lives.
Touka Kirishima could also be a fascinating crossover character. She's a strong - willed and capable ghoul in Tokyo Ghoul. If she got her hands on the Death Note, she might use it to protect her friends and the ghoul community in a more discreet way compared to her usual more direct combat methods. It would show a different side of her character, as she'd have to be more calculating and less impulsive.
A plot might involve a ghoul ending up in the Loud House world. This ghoul could be on the run from other ghouls or the CCG in its own world. In the Loud House, it has to hide its true nature from the Loud family while also trying to adapt. The Loud kids start to notice strange things happening around the house, like missing food (because the ghoul needs to eat). Eventually, they discover the truth and have to decide whether to help the ghoul or turn it in.
Naruto himself would be very interesting. His never - give - up attitude and powerful jutsu would make him a great addition to the AOT world. He could inspire the people there to keep fighting against the Titans. His ability to make friends easily might also help in uniting different groups in the AOT world.
I think Naruto himself. His never - give - up attitude and his ability to make friends easily would make for great interactions in FF14. He could inspire the other players or characters in the game to be more brave and determined.
One interesting storyline could be where the characters from Loud House find themselves in the universe of Outlaw Star. Maybe the Loud siblings end up on the Outlaw Star ship and have to adapt to the space - faring life. They could learn about the different alien species and technologies there. For example, Lincoln might befriend Gene and they could go on adventures together, with Lincoln's unique family - oriented perspective adding a new dimension to their space escapades.
I think Jack Sparrow from 'Pirates of the Caribbean' would be really cool to cross over with Hercules. Jack's wily and unpredictable nature would contrast with Hercules' more straightforward heroism. They could be on a quest for a magical artifact that has the power to either save or destroy the world. It would be full of adventure, humor, and unexpected twists.
Luna might be a bit of a wild card. Her love for rock music and her sometimes rebellious nature could be twisted into the dark side. She might be lured by the power of the Sith, thinking it would make her an even greater rock star in the Star Wars universe. But in the end, her family would probably try to bring her back from the dark side.
I think Luna from the Loud House would be really interesting. She has that rocker vibe which could mesh well with the spooky and unique nature of the ghouls. And then there's Spectra Vondergeist from Ghoul School. She could use her ghostly abilities to have some cool interactions with the Loud kids. Maybe she could play pranks on them that are more friendly than scary as they get to know each other.
Hope Mikaelson would be really interesting. She has such a powerful combination of magic and her werewolf/vampire heritage. In the Harry Potter world, she could be a real force to be reckoned with. She might be able to teach the Hogwarts students some new ways of using magic, or she could get involved in the fight against the Death Eaters and show them a whole new level of combat magic.
Definitely Naruto himself. He has such a unique personality and a wide range of powers. His positive attitude and determination would contrast greatly with the often dark and cynical world of GTA V. He could bring a sense of hope and justice to the criminal - filled streets of Los Santos. For instance, his never - give - up spirit would make him a force to be reckoned with when facing the various gangs and criminals in the game.
